I’m not sure why that is. Maybe it’s just more simple. Maybe it’s more practical. Odds are, though, that it’s just a cool motif for a story, and if you can get some spaceships or motorbikes in there, too, it’s like a bonus.

Trials Frontier, the latest in publisher Ubisoft’s physics-driven racing game franchise is out now, and it takes place in a rustic, post-apocalyptic world. But if you don’t care about that stuff, it’s also the series’ first appearance on mobile. And it’s free to play. And it’s really, really good.
